第一次未加载选项卡项图像

Question

我在我的项目中使用tabbarcontroller。这是我的故事板

​

​

在所有视图控制器选项卡项中，我设置了如下图像

我创建了一个tabbarcontroller类，并在下面进行了编码

    UITabBar *tabBar = self.tabBar;
    UITabBarItem *tabBarItem1 = [tabBar.items objectAtIndex:0];
    UITabBarItem *tabBarItem2 = [tabBar.items objectAtIndex:1];
    UITabBarItem *tabBarItem3 = [tabBar.items objectAtIndex:2];
    UITabBarItem *tabBarItem4 = [tabBar.items objectAtIndex:3];
    UITabBarItem *tabBarItem5 = [tabBar.items objectAtIndex:4];

//    [tabBarItem1 setImage:[[UIImage imageNamed:@"ic_home_tab_home_sel"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];
//    [tabBarItem1 setSelectedImage:[[UIImage imageNamed:@"ic_home_tab_home_sel"] imageWithRenderingMode:UIImageRenderingModeAlwaysOriginal]];




    [tabBarItem1 setFinishedSelectedImage:[UIImage imageNamed:@"ic_home_tab_home_sel"] withFinishedUnselectedImage:[UIImage imageNamed:@"ic_home_tab_home"]];
    [tabBarItem2 setFinishedSelectedImage:[UIImage imageNamed:@"ic_home_tab_profile_sel"] withFinishedUnselectedImage:[UIImage imageNamed:@"ic_home_tab_profile"]];
    [tabBarItem3 setFinishedSelectedImage:[UIImage imageNamed:@"ic_home_create_post_sel"] withFinishedUnselectedImage:[UIImage imageNamed:@"ic_home_create_post"]];
    [tabBarItem4 setFinishedSelectedImage:[UIImage imageNamed:@"ic_home_tab_chat_sel"] withFinishedUnselectedImage:[UIImage imageNamed:@"ic_home_tab_chat"]];
    [tabBarItem5 setFinishedSelectedImage:[UIImage imageNamed:@"ic_home_tab_setting_sel"] withFinishedUnselectedImage:[UIImage imageNamed:@"ic_home_tab_setting"]];

但当我运行它时，

第一次，所有的图像都是混合的，但当我像在Video中那样一个接一个地单击它们时，然后是所有图像集。

我不知道为什么会这样？

请帮帮我

谢谢

我也遇到了同样的问题，然后我用appdelegate编写了下面的代码

 UINavigationController *navigationVC1 = [[UINavigationController alloc]initWithRootViewController:viewController1];
    navigationVC1.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"My Trips"
                                                             image:[UIImage imageNamed:@"cab.png"]
                                                               tag:1];

    UINavigationController *navigationVC2 = [[UINavigationController alloc]initWithRootViewController:viewController2];
    navigationVC2.tabBarItem = [[UITabBarItem alloc] initWithTitle:@"My Children"
                                                             image:[UIImage imageNamed:@"kids-couple.png"]
                                                               tag:2];

试着这样做。
